    • Narrow size that makes it work well with aero bar extensions
Size: 25.4 x 90mm
Most stems are too wide for extra room to add aero extensions for special road drop bars. But this is pretty narrow, so I was able to make it fit. And its cheap too. Some things are good when made in China.

    • Great handle bar adjustment
Size: 25.4 x 110mm
Nice addition to my bike. It allows me to adjust my handle bar higher for a more relax riding position. Easy to install on my Scott Speedster. All tools are included.

    • Does exactly what I wanted it to do!!
Size: 25.4 x 90mm
Seems well made. No installation instructions but You Tube showed me how to do it. Didn't have to remove any handlebar attachments. Really pleased with purchase. It's installed on a G-Force T42 folding Bike. Rode it for several hours today on first test of the stem and all works well. No "tiller" effect as some have noted. Steering doesn't seem affected at all, but having the handlebars closer to my seated position was the point, and this accomplished that. ... show more

    • A bit creaky
Size: 25.4 x 90mm
Slight creak when pulling hard but that was expected. Easy, positive adjustment. I used this to turn an old mountain bike into a trail cruiser and it suited that purpose well.

    • Works perfectly!

This stem adjuster works perfectly on my Lectric 2.0. It allows me to bring the handle bars closer to me and allows me to adjust to the perfect angle. My hands are no longer going numb, because of having to reach.

    • Nice change, but don't use the bolts!
Size: 31.8 x 90mm
I love how my bike handlebars were transformed, for I am an older rider who needs the handlebars closer and higher. However, when installing, one bolt snapped and broke! After extracting it, I decided to use the old bolts from the replaced part. Highly recommend that all do so or ride at your own risk. ... show more
